MILK-AERATOR.

SPECIFICATION forming part of Letters PatentNo. 589,774, dated September7, 1897. Application iiled June 4, 1897. Seriallio. 639,456. (No model.)

citizen of the United States, residing at Au# rora, in the county ofKane and State of llli nois, have invented certain new and usefulImprovements in Milk Aerators and Strain ers; and l do hereby declarethe following to be a full, clear, and exactdescription of theinventiomsuch as will enable others skilled in the art to which itappertains to make and use the same. Y

My invention relates to improvements in milk aerators and strainers; andthe object that lhave in view is to provide a simple and inexpensiveconstruction in which provision is made for thoroughly straining themilk, for dividing the milk into thin streams during its passage throughthe aerator, and for free circulation of air around and through the thinstreams of -niilk While passing from the reservoir to the tray of theacrator.

Another clogect of myinvention is to provide for the ready and easyseparation of the parts, so that access may be had to all the parts ofthe aerator for the purpose of thoroughly cleaning thc same and fordrying` them previous to storing the device.

lith these ends in View my invention consists in the construction andcombination of parts,Which will be hereinafter fully described andclaimed.

To enable others to understand my invention, l have illustrated thepreferred embodiment thereof in the accompanying drawings, forming apart of this specification, and in Which- Figure l. is a perspectiveView of my iniproved strainer and aerator. Fig. 2 is a vertical centralsectional elevation thereof. Fig. 8 is a View of the tray and standdetached from the reservoir. Fig. 4 is a bottom plan View of thereservoir. Fig. 5 is an inverted perspective View of the strainer.

Like numerals of reference denote corresponding parts in all the figuresof the drawings, referring to Whichl designates the reservoir, 2 is thestrainer, is the tray, and a is the stand, the detailed construction ofwhich Will now be fully described.

The tray 3 has a slightly conical bottom 5,

the center or apex of which is in alineinent with the axis of thereservoir l. The tray bottom has a boundary iiange t5, which rises abovethe apex of the bottom 5, and in this flange, next to the bottom, isproduced an outlet-opening 6', through which the strained and cooledmilk may flow into a pail or other vessel. On the bottom of the tray iserected the stand 4, that serves to support the reser- Voir l in anelevated position above the tray, and the stand is constructed withsmall Wire legs which offer practically no obstruction to thecirculation of air through the thin streams of milk as they pass fromthe reservoir to the tray. The stand shown in the drawings consists oftwo pieces of wire 7 S, which are bent to provide legs and cross-bars,and the wires are arranged at right angles, so that the bars thereofcross one another, as shown by Fig. 3, the legs being fastened to thebottom of the tray and the cross-bars being united together, preferablyby soldering the parts together. This stand is arranged centrally on thetray and when the reservoir is disconnected therefrom the tray and standare exposed, so that they maybe thoroughly cleaned and dried.

The reservoir consists of a cylindrical vessel having a perforatedbottom, an open top, and a flange or rim 9, attached to the bottom, soas to embrace the stand and hold the reservoir thereon. The bottom' ofthe reservoir has a number of circular series of small holes 10, and theflange or rim 9 is att-ached to the bottom between two adjacentconcentric rows of holes. The diameter of this flange lO is equal to thewidth across the top of the open Wire stand, and the head of the standis adapted to rest against an imperforate part of the bot-tom betweenthe rows of perforations, so as 'to prevent any obstruction to theoutflow of milk through the perforations l0. The reservoir rests firmlyon the top or head of the stand and the liange lits up to and againstthe stand, so as to bear against the legs thereof and thus assist inholding the reservoir firmly on the stand. In fact, the annular rim ismade to lit tightly on the stand, so as to engage frictionally tightlytherewith to overcome any tendency of the reservoir to tilt and slip onthe stand, but the parts may be separated bya slight pull, so as todiscon neet the reservoir from the stand.

IOC

The Strainer 2 is an annular shell terminating at its lower end in aninverted conical bottom 11, in the center of which is a large openingcovered by wire-gauze or other foraminous material 12, forming thestrainer. This gauze 12 is reinforced by the arched crossed wires 13,which are arranged below said gauze and are attached to the bottom ll.The diameter of the strainer-shell is slightly less than that of thereservoir, and the strainer is provided with bent arms 14, which areattached to the outside of the shell at the place where the cone bottom11 joins the cylindrical shell, said arms being braced bythe inclined`strut-s 15. The strainer is placed on the open top end of thereservoir, so that the arms 14 rest upon the top edge of said reservoirand the conical bottom of the strainer extends down into the reservoirto terminate below said open end of the reservoir, an annular Spacebeing left between the strainer and the reservoir for the freecirculation of air to and from the reservoir.

It will be noted that the strainer is supported on the reservoir todirect the milk therein with a minimum waste of the milk, thus servingsomewhat as a funnel to direct the milk into the reservoir, and saidstrainer may be easily lifted off the reservoir and replaced thereon.

To use the device, the tray is placed on a suitable shelf or table with.its flanged edge having the opening t) extending beyond the shelf ortable to enable a pail or other receptacle to be' placed beneath thetray, so as to receive the milk as it iiows from the tray.y

The reservoir is placed in an upright position on the stand, so as tobe'sustained some distance abov-e the tray, and the strainer is placedover the reservoiigon which the strainer is supported by the bent arms.Milk can now be poured into the strainer, so as to leave its solidimpurities caught by the gauze 12 and thus retained in the strainer andthe milk passes into the reservoir 1. The milk then flows in minute thinstreams through the perforations 10 in the bottom of the reservoir andit descends upon and is caught by the tray 3, the conical bottom ofwhich deflects the milk to the side, so that it flows around the channelformed by the conical bottom and the flange toward the outlet-port.

As the milk emerges in thin streams from the reservoir it is exposed tothe air, which circulates freely between the reservoir and the tray, andthe milk is thus cooled rapidly.

It will be understood that the parts are easily separated to free them,so that they may be washed and then dried by exposing them to the sun orto heat. rl`he parts may be easily assembled together.

The device is simple and durable in construction and cheap ofmanufacture.

Having thus fully described my invention, what Iclaim as new, and desireto secure by Letters Patent, is-

1. In a milk aerator and strainer, the combination of a tray, having anroutlet at its bottom, a stand erected on the tray, a reservoir having aperforated bottom and an annular depending flange secured to animperforate portion of the bottom within its outer eircum ference, andadapted to t over the outside of the stand and be held in engagementtherewith by friction and to be removed therefrom when desired,substantially as described.

2. In a milk aerator and strainer, the combination of a tray having asuitable outlet at its bottom, a stand erected on the tray, a reservoirwith a perforated bottom and an annular flange for removably securing itto the outside ofthe legs ofthe stand, and a strainer of smallerdiameter than the cylinder and provided with depending legs or feet fordetachably securing it to said cylinder and to provide a circumferentialair-space between it and the cylinder, substantially as described.

3. In a milk aerator and strainer, the tray having a conical bottom andan outlet in one side thereof, a wire stand erected on the tray l andbavin the strands thereof crossing one Vanother at the upper end of saidstand, combined with a reservoir having a perforated bottom and anannular flange or rim on an imperforate part of the bottom arranged tofit frictionally tight upon the upper end of said stand, substantiallyas and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.
